I've been riding with various randonneurs for a long time. I notice that almost all of the better (faster) riders use a cadence of ~100 on the flat and quite a high cadence climbing also, maybe 85 or so. I think the idea is that a higher cadence uses more oxygen but spares glycogen which starts to become a bigger deal in rides over 200k. So trying to increase my self-selected cadence is one of the big things I'd work on over the winter.
